Agree with aquinas and 22b - she's discouraging thinking and trying to spare herself thinking, which strongly suggests incompetence. No support from the principal? Really? Even if these examples are literally true?

Also, I don't attend meetings with people who don't tell me what they're about. The only exception would be if that person had direct authority over me at work (where noone would dream of such discourtesy!) so that I couldn't refuse.

Assuming you've already agreed to the meeting, yes, listen, and then do whatever it takes to get your DD out of there.
